FreeCAD MCP (Model Control Protocol)

Overview

The FreeCAD MCP (Model Control Protocol) provides a simplified interface for interacting with FreeCAD through a server-client architecture. This allows users to execute commands and retrieve information about the current FreeCAD document and scene.

Features

The FreeCAD MCP currently supports the following functionalities:

1. get_scene_info

  • Description: Retrieves comprehensive information about the current FreeCAD document, including:
    • Document properties (name, label, filename, object count)
    • Detailed object information (type, position, rotation, shape properties)
    • Sketch data (geometry, constraints)
    • View information (camera position, direction, etc.)

2. run_script

  • Description: Executes arbitrary Python code within the FreeCAD context. This allows users to perform complex operations, create new objects, modify existing ones, and automate tasks using FreeCAD's Python API.

Example Usage

To use the FreeCAD MCP, you can connect to the server and send commands as follows:

import socket
import json

# Connect to the FreeCAD MCP server
client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect(('localhost', 9876))

# Example: Get scene information
command = {
    "type": "get_scene_info"
}
client.sendall(json.dumps(command).encode('utf-8'))

# Receive the response
response = client.recv(4096)
print(json.loads(response.decode('utf-8')))

# Example: Run a script
script = """
import FreeCAD
doc = FreeCAD.ActiveDocument
box = doc.addObject("Part::Box", "MyBox")
box.Length = 20
box.Width = 20
box.Height = 20
doc.recompute()
"""
command = {
    "type": "run_script",
    "params": {
        "script": script
    }
}
client.sendall(json.dumps(command).encode('utf-8'))

# Receive the response
response = client.recv(4096)
print(json.loads(response.decode('utf-8')))

# Close the connection
client.close()
